for MacOS 10.10.5 ?

Which Acrobat versions will run on MacOS 10.10.5 ?

[try67]

No current version sold by Adobe. I think Acrobat XI was probably the last one compatible with this version, maybe Acrobat 2015.

OS X 10.10 itself has been out of Apple's support for many years now.
No software manufacturer will support something that is no longer supported by the OS manufacturer.
We recommend that you migrate to a supported OS version as soon as possible.
(Currently supported OS versions are 10.15 and later.)

Any clue what MacOS is needed to tun Adobe Acrobat XI Pro 11.0.3 ?

According to this page it's Mac OS X v10.6.4, Mac OS X v10.7.2, or Mac OS X v10.8.

Im not reffering to Acrobat Reader but the full version of Acrobat.

The system requirements are the same.
